A 10.00 ml sample of an aqueous solution of calcium hydroxide is neutralized by 20.00 ml of 0.02000 m hno3 (aq. what is the molarity of the calcium hydroxide solution?

The chemical reaction would be as follows:

Ca (OH) 2 + 2HNO3 = Ca (NO3) 2 + 2H2O

We are given the concentrations and volumes of the substances. We use these values and the relationships to calculate the molarity of the Ca (OH2).

0.02 mol HNO3 / L (.02 L) (1 mol Ca (OH) 2 / 2 mol HNO3) = 0.0002 mol Ca (OH) 2

Molarity = 0.0002 / 0.010 = 0.02 M Ca (OH) 2
